1. Regarding the “Mazovian call for help” the question under dispute is not whether or not the duke understood “Poland's real interests” or showed “political foresight.” It is rather the question what his actual situation was or what he thought it to be. While St. Zajaczkowski maintains that the duke was “not in despair” (Kwartalnik Historyczny, XLVIII, 4, p. 843; quoted from a German translation) and while St. Ketrzynski calls the duke “allegedly desperate” and a “benefactor” of the Teutonic Order (ibid. p. 801), it still seems to me that Professor Halecki is more correct in admitting, that the “duke himself acted in despair.” I did not intend to do him injustice by stating a difference from “other” (I did not say “the” other) Polish historians.
